U2OS cells were seeded overnight at 40,000 cells per 100 μL per well in a 96-well black wall/clear bottom costar plate. The growth medium was removed, and the cells were incubated with 100 μl of 4 μM Fluo-4 AM or Fluo-8® AM in HHBS at 37 °C, 5% CO2 incubator for 1 hour. The cells were washed twice with 200 μl HHBS, then imaged with a fluorescence microscope using FITC channel.

FFA treatments increase Ca2+ influx to induce ERS in β-TC3 cells.

β-TC3 cells were incubated with FFA or BSA for 16 h, and then stimulated with 4 μM thapsigargin for 20 min to activate store-operated Ca2+ entry. Fluorescence densities of Ca2+ change were monitored in Fluo-8/AM-loaded β-TC3 cells after FFA or BSA treatments.

생물학적 정보

Medium affinity green fluorescent calcium binding dye. Binds to intracellular calcium (Kd = 390 nM). Fluorescence intensity increases upon Ca2+ binding. Cell-permeable.

Fluo-8 (or Fluo-2 Medium Affinity) has been found to be brighter (1.5x) than Fluo-4 in cellular experiments. It offers improved cell loading and Ca2+ response while maintaining the convenient Fluo-3 and Fluo-4 spectral wavelength of maximum excitation at 490 nm and maximum emission at 520 nm. Fluo-8 loading can be performed at room temperature.

제품 세부 정보

Fluo-8® AM Working Solution: On the day of the experiment, either dissolve Fluo-8® AM in DMSO or thaw an aliquot of the indicator stock solution to room temperature. Prepare a dye working solution of 2 to 20 µM in a buffer of your choice (e.g., Hanks and Hepes buffer) with 0.04% Pluronic® F-127. For most cell lines, Fluo-8® AM at a final concentration of 4-5 μM is recommended. The exact concentration of indicators required for cell loading must be determined empirically.

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
